Hello, I had the good fortune to AB 3 speaker cable brands all within a price range of 500-1,000 USD for 7.5 ft length. Kimber Cable12TC, Nordost Bue Heaven and Cardas Parsec. I did use any measuring tools so my "analysis" (also a great cable mfr) is purely anecdotal and subjective (how do I respond to to the music). Kimber Cable was overkill for my modest system (Hegel H90, Bluesound Node 2i and Focal Electra 1080 BE (bought new in 2018). Focal's are not difficult to drive.
Nordost Blue Heaven sounded a bit technical in the high end and did not seem to reach down to the lows as far as the the Cardas Parsec did. I went with the Cardas cable and coudn't be happier. As they became more aquainted with my components, the sound opened up. I would say they were the most neutral with a bit of warmth that interacted well with the glorious warmth of the Hegel, and spectacular highs of the Beryllium tweeter. The soundstage is, as you would expect with Bookshelf speakers, very accurate. I have the Focals sitting on top of ruggedly elegant and highly functional (and pricet), Sound Anchor stands which enhances the bass response substantially. Good luck choosing!!
